Grape rot

Many grape diseases affect the grapes on the vine, often as a result of various diseases with different causes and pathogens. These can also occur in combination. It is therefore a group with the common feature of grapes affected by rot.

Causes

Rot on grapes is caused by various microorganisms such as bacteria, yeasts and moulds. A distinction is made between primary infestation of healthy berries by Aspergillus, Botrytis, Cladosporium, Penicillium and Trichothecium, and secondary infestation by harmful birds, insects and weather(hail, rain, lightning) or berries damaged by primary infestation. Vinegar rot can also occur on the damaged berries. Grape rot is also favoured by a lack of nutrients in the vine during growth, such as nitrogen. Compact, dense-berried grapes are particularly at risk.
